Contribución al estudio de las Tortugas marinas en las costas españolas: I, distribución
An extensive compilation of the available literature regarding marine Turtles on the spanish coasts have been completed, giving at the same time further unpublished observations. The 99 references obtained are shared between ...
Contribución al conocimiento de Rana temporaria L. (Amphibia, Ranidae) en Sta. Fe del Montseny (Barcelona): I. Descripción de la zona y estima de la población
The area of the Montseny mountain whre the population of Rana temporaria lives is described. That mountain is part of the Catalonian Prelitoral System, so that it is clearly influenced by the mediterranean climate. ...

The developmental biology of Calotriton arnoldi: an analysis of the speed of growth of accidentally amputated extremities
A pesar de ser objeto de varios proyectos de conservación, gran parte de la biología y fisiología del amenazado tritón del Montseny (Calotriton arnoldi) es aún desconocida. Este estudio compara la velocidad de regeneración ...
Moult nestedness and its imperfections: insights to unravel the nature of passerine wing-feather moult rules
Passerine moult shows two well-known although intriguing characteristics: 1) a varying subset of wing feathers are retained during certain moult episodes, and 2) the identity of the replaced feathers is not random. However, ...
On the meat scavenging behavior of House Sparrows (Passer domesticus)
Behavioral plasticity can drive feeding innovations, a frequent trait of urban exploiter species. The House Sparrow (Passer domesticus) is a widespread and abundant urban dweller whose success has often been related to its ...
The impact of prolonged frozen storage on the preparation quality of bird skins and skeletons in zoological collections
Specimens from zoological collections play a pivotal role in improving scientific knowledge in many natural science disciplines. To guarantee an optimum state of conservation and ensure their usefulness, the preparation ...
A revision of bird skin preparation aimed at improving the scientific value of ornithological collections
The methods used to preserve bird skins in museums have a potentially crucial impact on the feasibility and use of these specimens as a source of biological knowledge, although this subject is rarely broached. Study skins ...
A plastic device fixed around trees can deter snakes from predating bird nest boxes
Several devices have been designed to prevent predation in nest boxes by mammals and birds. Although snakes are one of the most common predators in cavity–nesters, they have always been difficult to deter. Here we tested ...
Preformative molt in Neotropical Cardinalidae
Neotropical Cardinalidae consists of 40 species in 10 genera that have diversified across the Americas. We provide quantitative information on the preformative molt of 21 Cardinalidae species of seven genera, plus one ...
Partial or complete? The evolution of post‐juvenile moult strategies in passerine birds
Moulting strategies in birds have evolved to avoid overlap with, or prepare for, other demanding parts of the annual cycle, such as reproduction or migration. When moulting for the first time after leaving the nest, young ...
What’s next? The release of exotic pets continues virtually unabated 7 years after enforcement of new legislation for managing invasive species
There are many pathways by which invasive species are introduced and become established, with the exotic pet trade becoming an increasingly important route. The abandonment of pets is a growing problem, which has been ...
Superciliums in white-eared hummingbirds as badges of status 2 signaling dominance
The role of badges as indicators of contest ability has been previously described. In hummingbirds, the exhibition of a badge is expected to save energy expenditure in agonistic interactions and to favor energy intake. ...
Stay or leave? Avian behavioral responses to urbanization in Latin America
Behavioral adjustments are at the forefront of the mechanisms that birds employ to deal with environmental changes. We here review the literature focused on how behavior influences bird responses when faced with the ...
Are invasive House Sparrows a nuisance for native avifauna when scarce?
Biological invasions are the second most important cause of species extinction. Aided by processes such as transportation and urbanization, exotic species can establish and spread to new locations, causing changes in the ...
On the lookout for danger: House Sparrow alert distance in three cities
The House Sparrow Passer domesticus, closely associated with human presence along urban–agricultural landscapes and widely distributed outside its native range, has shown great morphological and physiological variations, ...
